Embodiment one
As shown in Fig. 2, the embodiment of the present invention provides a kind of production method of touch-control display module, comprising the following steps:
A glass substrate is provided as cover board；
CF matrix layer and touch function line layer are produced on to the lower end surface of glass substrate, the upper sheet glass for display panel；
The lower sheet glass of one display panel is provided, upper sheet glass and bottom sheet glass gluing are formed into touch-control display module.
Specifically, the glass substrate had both been used as the cover board of touch-control display module, while being used as upper piece glass of display panelCF(COLOR FILTER) matrix layer is first produced on lower end surface (this production method and the existing skill of glass substrate by the substrate of glassThe method that CF matrix layer is made on the display panel of art is identical, and CF matrix layer is used to provide colored display for touch-control display module),Four chow ring of lower end surface of glass substrate is set up defences the black out ink that the light of only CF matrix layer leaks out outward；Again by touch function lineRoad floor is produced on the lower end surface of the glass substrate with CF matrix layer；Then, the lower sheet glass of a display panel, the bottom sheet are providedThe upper surface of glass is formed with display panel functional circuit layer, and lower sheet glass is formed with to the side of display panel functional circuit layerThe side for being formed with CF matrix layer and touch function line layer with upper sheet glass be bonded forming touch-control display module.It is bondedMethod can be the epoxy glue laminating set by four chow rings, but not limited to this, wherein touch function line layer avoids epoxy glueSetting.
The region that black out ink described in the embodiment of the present invention is formed can be used as the non-display area of touch-control display module, instituteThe region for stating the formation of touch function line layer can be used as the viewing area of touch-control display module.
The production method of the touch-control display module of the embodiment of the present invention eliminates on the touch screen film or glass, display panelThe material of sheet glass, two layers joint adhesive, also eliminates and is bonded cover board with touch screen, then touch screen is bonded with display panelThe fabrication steps such as technique integrate display panel, touch screen and cover board using three-in-one technique, save material, reduce workSection reduces cost, also has many advantages, such as customization.
As a further improvement, the lower sheet glass of the display panel, which can be TFT glass, is also possible to OLED glass.
Before the upper sheet glass and bottom sheet glass gluing, also there is the step of binding FPC, and after fitting, pass throughFPC is electrically connected to the display function and touch function that driving IC realizes touch-control display module.
Metallic conduction particle, the display panel function electricity of lower sheet glass are mixed in epoxy glue described in the embodiment of the present inventionRoad floor is electrically connected on upper sheet glass by metallic conduction particle, then is connected in control mainboard by FPC.It can also be drivingIC is connected in control mainboard by FPC again after being also bundled on sheet glass.
As a further improvement, further including the upper end face paste in glass substrate in the production method of the touch-control display moduleConjunction has the step of polaroid, which can carry out after upper sheet glass and bottom sheet glass gluing, can also upper sheet glass withIt is carried out before bottom sheet glass gluing.
As a further improvement, further including the upper sheet glass in display panel in the production method of the touch-control display moduleLower end surface the step of being fitted with polaroid, i.e., in the lower end that CF matrix layer and touch function line layer are produced on to glass substrateThe fitting of polaroid is carried out after face again.
As a further improvement, further including the lower end wheat flour in glass substrate in the production method of the touch-control display moduleBefore making CF matrix layer and touch function line layer, in the step of lower end surface of glass substrate is fitted with polaroid.
It should be understood that the present patent application focus on for CF matrix layer and touch function line layer being integrated in it is sameOn a glass substrate, and prior art conventional technique can be used in CF matrix layer and the specific production method of touch function line layerMeans, the present patent application are not specifically addressed.
